See https://linuxtv.org/wiki/index.php/Astrometa_DVB-T2 for the full status, paying attention to the comment about the update in 2018. Support for the 2018 update appears to have been added in Linux 5.0, whilst we're supporting 4.19 (it is a long term support kernel). If you have a 2018 variant then you'll need to build your own kernel.
